简要总结
Urge urinary incontinence is a prevalent condition characterized by involuntary leakage of urine accompanied by a sudden, compelling urge to void. It significantly impairs quality of life and is associated with substantial physical, psychological, and social burden. Noninvasive treatment modalities, including pulsed electromagnetic field (PEMF) therapy and posterior tibial nerve stimulation (PTNS), have gained attention due to their safety and ease of application.
This study is designed as a prospective, randomized, assessor-blinded clinical trial conducted in women diagnosed with urge urinary incontinence. Eligible participants will be randomly assigned to one of two intervention groups: PEMF therapy or tibial nerve stimulation. Both interventions will be applied over a predefined treatment period under standardized conditions.
Outcome measures will include symptom severity, frequency of incontinence episodes, and quality of life, assessed using validated instruments such as the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), bladder diaries, and quality-of-life scales. Assessments will be performed at baseline and after completion of the treatment period.
The primary aim of the study is to compare the efficacy of PEMF therapy and tibial nerve stimulation in reducing urinary symptoms. Secondary objectives include evaluating improvements in quality of life and functional outcomes. The findings of this study are expected to contribute to the optimization of noninvasive treatment strategies for urge urinary incontinence.
详细描述
This study is designed as a two-arm, parallel-group, prospective, randomized, assessor-blinded clinical trial. Participants will be randomly assigned in a 1:1 ratio to either the pulsed electromagnetic field (PEMF) therapy group or the tibial nerve stimulation group. Randomization will be performed using a computer-generated simple randomization method.
The outcome assessor will be blinded to group allocation to minimize assessment bias. Both treatment modalities are noninvasive and commonly used in the management of urge urinary incontinence. Treatment allocation will be determined solely by randomization rather than clinical indication, as the primary aim of the study is to compare the efficacy of these two interventions. Therefore, no participant will be deprived of standard care.
A total of 40 female patients will be included in the study, with 20 participants in each group. Only women aged between 18 and 65 years will be recruited to ensure a homogeneous sample and to account for anatomical and physiological differences in the pelvic floor.
Both groups will receive a standardized pelvic floor exercise program in addition to their assigned treatment. The treatment duration will be 6 weeks, consisting of 18 sessions in total. During the first 2 weeks, treatments will be administered 5 days per week, followed by 2 sessions per week for the remaining 4 weeks.
The primary outcome measure will be the change in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) total score. Assessments will be performed at baseline (pre-treatment), at the end of treatment (6th week), and at the 10th-week follow-up. A validated Turkish version of the questionnaire will be used, and all assessments will be conducted by an independent blinded evaluator.

结局指标
主要结局
Change in ICIQ-UI Short Form Total Score
时间窗: Baseline, 6 weeks (end of treatment), and 10-week follow-up
The primary outcome is the change in the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF) total score. This validated questionnaire assesses the severity and impact of urinary incontinence on quality of life. A greater reduction in score indicates clinical improvement. Time Frame: Baseline, 6 weeks (end of treatment), and 10-week follow-up
次要结局
- King's Health Questionnaire(Baseline, Week 6, and Week 10)
